Well its the same sresult if I use the rollover, "open"
and if I use the straight thru it looks like this:
AS2511rj#telnet 172.21.25.11 2002
Trying 172.21.25.11, 2002 ...
% Connection refused by remote host

this is killing me.
And all these Con0's work with a straight thru console session and a pc
(with hyperterm, and SecureCRT) and I have tried through the 2511
console, through telnet through the console, and telnet from my desktop
through to the 2511 and then reverse telnet from those connections too!

2 rollovers from cisco (light blue) - the flat blue rollovers that I
had they must have not been made coorectly OR the cables relied on the
db9 "snap-in" connectors to make it a true rollover. I could not tell
by looking at thee nds of them if they were correct rollovers. . So I
made a plenum cat6 (all I had) rollover on my own and it worked like a
champ!! With No configs on the receiving Con0 and only "no exec" and
"preferred telnet" under lines 1 16 on the 2511. On thing is for sure
My humble advice:
Building your own lab brings you all kinds of "accidental" knowledge.
Unbelievable, painful, but good solid learning. I know now more than I
ever wanted about async's and rollovers and 2511's!
A big Thank you.
